need repositoryUrl build variable for BitBucket

Problem:

Unable to retrieve Bitbucket repository URL using Bamboo variables
Documentation: Bamboo variables

Duplication Steps:

1. Create build plan
2. Add Bitbucket repository to build plan
3. Add ${bamboo_repository_git_repositoryUrl} to startup script
4. Run build
   URL not returned

Workaround:

Use Bitbucket REST API:

curl -u [username] -p -H GET https://api.bitbucket.org/2.0/repositories/[username]/[repo_slug]
